There is no online play present.Jam City Rollergirls is a fun experience, if a bit rough around the edges. If you're interested in a racing game with a bit of combat and a team sports element, this might be for you.
Jam City Rollergirls is a pretty neat, if ultimately not too heavy video game introduction to roller derby, and if you have even a passing interest in the sport may serve you well. While it could ultimately benefit from more, more, more, the game still manages to punch out a good time.
